There is a number of ways that this can be done but why not just put a
button on the page and call it home like this:
<form>
<input type="button" onclick="if (window.home) window.home()"
value="Your Home Page">
</form>
For trapping keys, I got this particular solution from a newsgroup,
comp.lang.javascript, a while ago and I have tested it and it does work.
The problem I see is that how can you deactivate or redirect the
existing hotkeys. All you need do is modify this script to suit your own
purposes. The only other issue to cover is alerting the user to the
availibility of the hotkeys for the purposes you want to put them to.
